> Hi Craig,
I have been trying to do something similar to the examples, just a little
different, it is the
Using typemaps to return
arguments<http://www.swig.org/Doc2.0/SWIGDocumentation.html#Java_using_typemaps_return_arguments>except
I would like the status, one int and one string to be returned.

my function is:

int gaiaTextReaderFetchField (gaiaTextReaderPtr reader, int field_num,
int *type, const char **value);

reader and field_num are input, status, type and value needs are output, so
I figure "Using typemaps to return arguments" is the way to go, however, as
in the example I would need to create structs (classes) for type and value
and populate them with the int and char ** respectively.

The populating of these two structs which would be done within a
typemap(out), I guessing, is where I am lost.

Not sure if much Java is done here, seems to be a lot of Python and Tcl,
very frustrated, not with anyone, just with my own lack of progress. So I
am searching for other learning sources.
